This commit removes `oss` storage driver from distribution as well as `alicdn` storage middleware which only works with the `oss` driver. There are several reasons for it: * no real-life expertise among the maintainers * oss is compatible with S3 API operations required by S3 storage driver Signed-off-by: Milos Gajdos <milosthegajdos@gmail.com>

# Building the registry source
|
|
|
|
## Use-case
|
|
|
|
This is useful if you intend to actively work on the registry.
|
|
|
|
### Alternatives
|
|
|
|
Most people should use the [official Registry docker image](https://hub.docker.com/r/library/registry/).
|
|
|
|
People looking for advanced operational use cases might consider rolling their own image with a custom Dockerfile inheriting `FROM registry:2`.
|
|
|
|
OS X users who want to run natively can do so following [the instructions here](https://github.com/docker/docker.github.io/blob/master/registry/recipes/osx-setup-guide.md).
|
|
|
|
### Gotchas
|
|
|
|
You are expected to know your way around with go & git.
|
|
|
|
If you are a casual user with no development experience, and no preliminary knowledge of go, building from source is probably not a good solution for you.
|
|
|
|
## Configure the development environment
|
|
|
|
The first prerequisite of properly building distribution targets is to have a Go
|
|
development environment setup. Please follow [How to Write Go Code](https://golang.org/doc/code.html)
|
|
for proper setup. If done correctly, you should have a GOROOT and GOPATH set in the
|
|
environment.
|
|
|
|
Next, fetch the code from the repository using git:
|
|
|
|
git clone https://github.com/distribution/distribution
|
|
cd distribution
|
|
|
|
If you are planning to create a pull request with changes, you may want to clone directly from your [fork](https://help.github.com/en/articles/about-forks).
|
|
|
|
## Build and run from source
|
|
|
|
First, build the binaries:
|
|
|
|
$ make
|
|
+ bin/registry
|
|
+ bin/digest
|
|
+ bin/registry-api-descriptor-template
|
|
+ binaries
|
|
|
|
Now create the directory for the registry data (this might require you to set permissions properly)
|
|
|
|
mkdir -p /var/lib/registry
|
|
|
|
... or alternatively `export REGISTRY_STORAGE_FILESYSTEM_ROOTDIRECTORY=/somewhere` if you want to store data into another location.
|
|
|
|
The `registry`
|
|
binary can then be run with the following:
|
|
|
|
$ ./bin/registry --version
|
|
./bin/registry github.com/distribution/distribution/v3 v2.7.0-1993-g8857a194
|
|
|
|
The registry can be run with a development config using the following
|
|
incantation:
|
|
|
|
$ ./bin/registry serve cmd/registry/config-dev.yml
|
|
INFO[0000] debug server listening :5001
|
|

|

|
|

|
|

|
|
|
|
If it is working, one should see the above log messages.
|
|
|
|
### Build reference
|
|
|
|
The regular `go` commands, such as `go test`, should work per package.
|
|
|
|
A `Makefile` has been provided as a convenience to support repeatable builds.
|
|
|
|
Run `make` to build the binaries:
|
|
|
|
$ make
|
|
+ bin/registry
|
|
+ bin/digest
|
|
+ bin/registry-api-descriptor-template
|
|
+ binaries
|
|
|
|
The above provides a repeatable build using the contents of the vendor
|
|
directory. We can verify this worked by running
|
|
the registry binary generated in the "./bin" directory:
|
|
|
|
$ ./bin/registry --version
|
|
./bin/registry github.com/distribution/distribution v2.0.0-alpha.2-80-g16d8b2c.m
|
|
|
|
Run `make test` to run all of the tests.
|
|
|
|
Run `make validate` to run the validators, including the linter and vendor validation. You must have docker with the buildx plugin installed to run the validators.
|
|
|
|
### Optional build tags
|
|
|
|
Optional [build tags](http://golang.org/pkg/go/build/) can be provided using
|
|
the environment variable `BUILDTAGS`.
